无线心电图仪可用于广泛的应用，包括早期检测癫痫发作、West综合征、睡眠呼吸暂停、颞叶癫痫(TLE)、室上性心动过速、心房扑动和心房颤动。在远程医疗中使用无线传感平台的优势之一是，在测量生命心脏动作电位的同时，患者可以不受阻碍地自由移动和进行日常活动。然而，测量对运动高度敏感，因为运动改变了电极和皮肤之间界面的电特性，从而使有用的信号失真。在本文中，我们提出了一种建立运动伪影统计量的策略。我们的方法使用3D加速度计来推断移动对无线心电图机电极的影响，并利用心脏动作电位的结构和顺序。
Wireless electrocardiograms can be useful for a wide range of applications including early detection of seizures onset, West Syndrome, sleep apnoea, Temporal Lobe Epilepsy (TLE), supra-ventricular tachycardia, atrial flutter, and atrial fibrillation. One of the advantages of using wireless sensing platforms in telemedicine is that patients can freely move and carry out everyday activities unhindered whilst vital cardiac action potentials are being measured. However, the measurements are highly sensitive to motion as motion changes the electrical characteristics of the interface between the electrodes and the skin and, thereby, distorts the useful signal. In this paper we propose a strategy for establishing the statistics of motion artefacts. Our approach employs 3D accelerometers to reason about the movement affecting the electrodes of a wireless electrocardiogram and takes advantage of the structure and sequence of cardiac action potentials.
